The present invention discloses a method of recovering lipase activity which comprises the steps of using a lipase derived from Thermomyces sp. and immobilized on a carrier, or a lipase powder composition which comprises a filter aid and the lipase derived from Thermomyces sp. and immobilized on a carrier which is crushed into the average particle size of 1 μm or larger and smaller than 300 μm in an esterification or transesterification reaction; and washing said lipase or lipase powder composition with triacylglycerol. According to this method, the decreased lipase activity can be effectively recovered.
